124 INSECTS INJURIOUS TO STAPLE CUOI'S. 



an car is badly infested give it a reddish tinge, on account 

 of which the insect is often called the '' Eed Weevil." 



When full-grown the larvae enter the ground and usually 

 form cocoons, in which they pass the winter in the pupal 

 stage, though they often hibernate without such protec- 

 tion. Though doubtless there is usually but one brood in 

 a season, observations by Prof. F. M. Webster and others 

 seem to point to the fact that there sometimes are two 

 broods, as adults have been observed from August into 

 November. 



Besides wheat, the wheat-midge also sometimes injures 

 rye, barley, and oats. 



Remedies. — Plowing infested fields in the fall so deeply 

 that the midges will be unable to reach the surface upon 

 developing in the spring is by far the best means of con- 

 trolling this 2^est; while burning the stubble previous to 

 plowing, and a rotation of the crop, will also be of con- 

 siderable aid.*
